Like dull dinner guests, parades get more interesting if you push them into the pool after it gets dark. Enjoy an evening of watery entertainment with today’s Groupon: for $10, you get one adult ticket to watch the Winterfest Boat Parade from the Grandstand viewing area in Birch State Park (a $21 value).

On Saturday, December 11, the 39th Annual Winterfest Boat Parade will delight an estimated one million guests with a nighttime march of brilliantly decorated boats, kicking off Fort Lauderdale’s Centennial celebration in the process. Today’s deal gets you an adult ticket for entry to the Grandstand viewing area, which opens at 3:30 p.m. and includes access to interactive, family-friendly games, live entertainment, arts and crafts, and refreshments. The boat parade begins its 12-mile water crawl downtown at 6:30 p.m., and by 7:30 p.m. appears at the Grandstand viewing area to astound the audience with a slow-motion stampede of brightly lit floaters, including The Clydey Foundation’s Centennial Cirque Showboat, the Sky Limo Airplane Barge, and the Baptist Health Santa Showboat, which illuminates the night with 1,500 LED lights to guide St. Nick back to his beachfront winter home.

A multicultural event that’s been promoting diversity and delighting crowds since 1971, the Winterfest Boat Parade stretches across Fort Lauderdale and features a different theme each year—2010’s theme will be “Dancing Thru the Decades.” Refresh your eyes with the colorful night sights and donate your spare cheers to compensate the boat decorators for the hundreds of hours they spent preparing their fancy flotillas.
